We at Kotaku have long been in the habit of reciting all major series games, whether it's Pokemon or Halo or Assassins Creed. At the glance, those comments may appear as reductive. Most every game has some redeeming quality. On the other hand, every perfect game probably has something to dislike about it. Hence the start of a new series here at Kotaku, where we discuss the singular best and worst aspects of every major series of loot-shooters.
